Problems with search button in toolbar. Custom Backend Modul

Hello, I have a question. I want know if the text to search in the search button of a custom module like locations can be modified to remove blank spaces. (Can see the image attached). My problem is that I display to the user the values with spaces between each word for example "Account Balance" but in the database the value saved is "AccountBalance" and when the user do a search writing with spaces, the search doesn't display nothing. But if write without space it works..! I know what is the issue but have not idea what can do for resolve this or if the search input in button could remove blank spaces.
